[Qgis-user] gdal_merge - GDAL Tools plugin Qgis error message

[William Kyngesburye]

I didn't know multiple paths could be used there (lack of documentation), though it makes sense.  Though pymod is not part of the problem, it's python itself.  So it should be:

/usr/bin:/Library/Frameworks/GDAL.framework/Versions/1.7/Programs/

Once Python is found in /usr/bin, the GDAL pymod will be in the python sys.path.

... and that works.

There is a hidden mechanism for setting Application environment, but I don't want to spread that as it is cluncky to use (need 3rd party apps for a nice GUI front end), and is not well documented, if at all.
